The Best Free Ways to Convert HEIC to JPG

Updated 2026-06-09

The best free HEIC-to-JPG converter for most people is image-cat: it batch-converts in your browser with no upload and no app install. CloudConvert handles more formats if you're fine uploading; on a Mac, Preview/Photos can export JPG natively.

HEIC is Apple's efficient photo format, but send one to a Windows user or upload it somewhere and it often just won't open. Converting to JPG fixes that. The questions that matter: does it batch, does it need an app, and do your photos get uploaded. We run a converter ourselves, so here's the straight version.

image-cat

Built by us

Best for: Anyone on any OS who wants to batch-convert without uploading photos.

Free, no sign-in, no watermark
Converts HEIC→JPG (and JPG↔PNG↔WebP↔AVIF) in-browser
Batch multiple photos at once
Photos never leave your device

First-hand notes

This is the exact case we built for: a folder of iPhone HEIC photos that won't open on a PC. Drop them in, batch-convert to JPG, done — no software install, and since it's local your photos aren't uploaded to anyone. Honest limit: converting changes the container, it can't add detail that HEIC didn't capture; and very large batches depend on your device's memory.

FAQ

Why won't my HEIC photos open on Windows?: HEIC is Apple's default and Windows doesn't fully support it out of the box. Converting the photos to JPG makes them open anywhere. A browser converter does this without installing the codec packs Windows otherwise needs.
Will converting HEIC to JPG reduce quality?: JPG is lossy, so a conversion re-encodes the image and can lose a little quality, though usually it's not visible. The bigger trade-off is file size: JPG is often larger than the original HEIC at similar quality. For sharing and compatibility it's worth it.
Is it safe to convert photos online?: If the photos are private, prefer a converter that works locally in your browser so they aren't uploaded. image-cat processes on your device; many popular converters upload to a server, which is fine for non-sensitive images but worth knowing.
